Hello all... I just picked up my very own Simpsons Pinball Party (my first machine ever) and I have a potential problem I was hoping somebody could help with. The machine tested out fine at the point of purchase but after getting it home and set up I've had trouble with the couch multiball. The couch doesn't want to hold the balls and just drains them to the lower playfield every time. I've been sure to hit the "light" and "lock" targets before sending the ball to the couch, but neither lights up when hit (bulbs fine... they flash, etc).
The multiball was not working Saturday (the day I brought it home) and Sunday afternoon. Then Sunday night I did notice it engage and hold the balls for a game or two. After that it has not held the balls.
I've restored factory settings, it didn't do anything. I took the glass off and manually hit the light/lock targets - they make a sound but don't light. I pushed on the end of the piston that keeps the balls on the couch and it popped out. I played a game, got 3 balls in the couch and they released with multiball. However, after release I was unable to get the couch to trap balls again in subsequent games.
Any ideas? The place I purchased it from is 1 hr 44 min away and sounds pretty reluctant to make a housecall. Hopefully my descriptions are accurate... as I mentioned this is my first machine so I am very inexperienced in pinball mechanics.
Thanks for any and all advice!
